FBD for Newton's Law of Motion Problem

Click For Summary

Homework Help Overview

The problem involves analyzing the forces acting on two connected blocks under the influence of an external force and friction, specifically using free body diagrams (FBD) in the context of Newton's laws of motion.

Discussion Character

  • Exploratory, Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • The original poster attempts to establish the relationship between tension and force using their FBD but expresses uncertainty about its correctness. Some participants suggest starting with equations and emphasize the importance of mathematical analysis in physics.

Discussion Status

The discussion is ongoing, with participants exploring different approaches to the problem. There is a mix of preferences for using FBDs versus equations, and some guidance has been offered regarding the use of mathematical methods.

Contextual Notes

The original poster indicates a step-by-step approach and seeks validation of their FBD, highlighting a potential lack of confidence in their initial setup. There may be constraints related to the specific homework guidelines or expectations for the solution process.

Homework Statement


In the figure, block 1 of mass m1 = 1.8 kg and block 2 of mass m2 = 1.4 kg are connected by a string of negligible mass. Block 2 is pushed by force Upper F Overscript right-arrow EndScripts of magnitude 18 N and angle θ = 34°. The coefficient of kinetic friction between each block and the horizontal surface is 0.16. What is the tension in the string?

This is my FBD(Is this right?)

I want to do it step by step..
my first thoughts it will be
T1-f=0 -> T1=f (block m1) but I don't know if this right can someone guide me to this question

Thank you and God bless!

Why don't you start with the equations. I prefer doing physics with actual math.
 
So far so good...sine and cosine for the right!

Okayyy but I got used to using FBD then proceed to do equations. But my problem is I don't know if my FBD is right
